1'0 all w/wm it may concern.-

Be it known that I, AUGUSTUS LEANDER ELLIS, a citizen'of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented a new liquids from which inflammable gasmay be made.

An ob ect of the invention is to provide positive, direct, and simplemeans for making from gasolene or other suitable liquid, a gas ofuniform quality, by supplying in correlative proportions to thecarbureter, air

and inflammable liquid, the former being supplied continuously and underuniform pressure while the gas is being used, and the .latter beingsupplied intermittently in appropriate quantities at intervals duringthe same time, thereby causing the air to always act upon a body offresh liquid, and .to-accomplish this in a most direct and positive wayand without any pump for the inflammable liquid. B y this means the samequality of gas may be produced throughout the entire period in which themachine is inoperation, and the liability to get out of order is broughtto a minimum.

In order to secure an absolutely uniform 4 gas at a uniform pressure atall times, it is necessary to supply the air and inflammable liquld tothe carbureterunder uniform conditions for each, and in order to do thisit is necessary that the air be delivered to the carbureter at apactically constant and uniform pressure, and that the liquid be suppliedunder sullicient pressure to spray it upon the absorbent material in thecarbureter, )ut in such small quantity as to prevent flooding of thecarburetor and overcharging the air. I therefore employ an aircmcterbetween the air pump and the carbure tor as a part of the means forsupplying the liquid and air in. correlative proportions; and

i. pro vide a gravity feed and a weighted rotary outsellvalve to controlthe flow therefrom to the carburetor, and I- operate said cut-oil byconnection with the belief an air pump.

Although my gas machine is ada ted for lug gas from any suitable liquidI shall after refer to liquid liiydrocar'bon as the The invention isapplicable in gas ma chines provided with an air pump by which the airto be carbureted is supplied, and. re-

lates to carbureting means, to means for supplying hydrocarbon and airin correlated proportions, and also to various features, con-i binationsand parts hereinafter particularly described.

Theinvention may be carried out in different forms and styles ofmachines, and I shall illustrate the same in one of the forms I deemmost desirable.

The carbureter in this invention is of novel construction and issupplied with liquid hydrocarbon that is directly under the control ofthe air-supplying means. The valve to control the supply of liquidhydrocarbon may be operated by the movements of an airometer or by themovements of an air pump, or by other means I shall illustrate theinvention as applied in a machine in which the hydrocarbon sup ply iscontrolled by the movements of an automatic air pump operated by watersupplied under .pressure to raise the bell or receiver of the air pumpand then automatically discharge to allow the receiver to descend. Thisform of pump being Well known, will not be illustrated in detail herein.

The accompanying drawings illustrate the invention in the form 1 atpresent deem preferable.

which is provided with a vertically-movable receiver or bell 2 that isooerated up and down in the usual way to pump air through to the airchamber 9.

a pipe 3 to an airometer 4 for equalizing and keeping at uniformpressure the air which isthence delivered through a pipe 5 to the lowerpart ofia carbureter 6. This uniform pressure of the air is necessaryorder to supply the air and hydrocarbon to the carbureter in correlativepro ortions. Said carbureter comprises a ,shel 7 provided at the topwith a hydrocarbon reservoir or tank 8, and at the bottom'with an airchamber 9.

10 is a diaphragm or partition forming the bottom of the tank 8, and 11is a diaphragm forming the bottom of the air chamber 9.

12 is a foraminated partition or support above the air chamber 9 forsustaining a layer of sponges 18.

14 is an air distributer in the form of a hollow cylinder or cap open atits lower end to receive air from the pipe 5 and distribute it Said pipe5 extends up into the cap 14 so that the air which enters the carbureteris forced to flow from the end of the pipe 5 downward and outward at thebottom of the cup to be evenly distributed to the under side of thelower sponges 13 which are carried by the foraminated partition 12. V

15 is a porous body which may be formed of excelsior above the layer ofsponges i3 and surrounding and overlying the upper end of the airdistributer 14, I

16 designates a top layer of sponges, and 17 a foramin'ated partition orscreen. above said'top layer, preferably made of Wire netting.

18 is a spreading device for distributinr liquid hydrocarbon over thenetting an porous filling.

19 is a valved conduit leading from the reservoir 8 above the'partition10 and opening into the carbureting chamber 20 through the hvdrocarbonspreader or star 18 which delivers the hydrocarbon to the porous bodies16, 15, 13, beneath the same, and all located in the carburetingchamber.

' 21 is a gas outlet-main leading from the top of the carburetingchamber 20 to the burners, not shown. 7

22 is an equalizing pipe communicating between the carbureter chamber 20and the top of theliydrocarbon reservoir 8 to supply the vacuum in thehydrocarbon reservoir, and. equalize the pressure on opposite sides ofthe diaphragm 10 as the hydrocarbon flows from chamber 8 into chamber20;

The purpose of providing a layer of porous 1naterial,preferablysponges,then a layer pension the smaller and-lighter particles ofydrocarbon, while the=heavier and larger particles of hydrocarbon willpass on through the fibrous material which will divide and break theminto smaller bodies, and the last or lower layer of porous material willhold them in suspension, thus .placing the entire amount of hydrocarbonsupplied at one action, to the carbureter, in sucha position that theair as it is supplied to the carbureter at a lower layer of porousmaterial, will come in contact first with the heavier or less volatilepart and afterward with the lighter, more volatile parts of thegasolene, and as it passes through the various layers of porous andfibrous material, will become charged with I sufficient hydrocarbon toproduce an even and fixed gas; The hydrocarbon being only supplied in-proportion to the air, does not permit thef air to be overcharged withthe ydrocarbon and compels the air to act more evenly and thoroughly onthe hydrocarbon, and

same;

An intermittent automatic hydrocarbon cut-oil device is provided in theform of a feed valveand operative parts connected therewith, which willnow be described.

23 is a feed valve for controlling the flow of so, insures a bettercarburizing f-the ICO liquid hydrocarbon through the valved conduit- 19,the same being operated by a suitable-trip 24 having a bell-crank orlever 25 loosely mounted on the valve-stem and adju'stable overbalancingweights 26 and 27' adjustably mounted respectivel'y'on arms 28 and 29,which arms are connected with an operating-arm 30 and with a sleeve 31adjustably fixed on valve stem 23 by set-screw 32. Integrally unitedwith said sleeve are the three arms numbered 28, 29 and 30, two ofwhih'h,namely 28 and 29, are provided with counterweights 26 and 27,previously, referred to. These weights are adjustable on said-arms bymeans of set screws 30. On the same stem 23 is fulcrumed a bell-crank orlever 25 provided at one end with an'elongated slot 34 and having a lugor pin 34 at the other end which is arranged to extend between andalternately engage the=arrn 30 and the arm 29. the bell-crank for thepurpose of allowing thr operating-rod 35 to extend therethroug'h. Uponthis rod are mounted adjustable members or buttons 36 which, whencontacting with the lever or bell-crank 25, on the rise and fall of thepump-bell, cause the pin or lug 34 to liftthe weighted arms up to andThe slot 34 is provided in over the center of gravity, whereupon thesame will fall and either. close or open the valve.

The operation of the rod 35 is controlled entirely by the movement ofthe air-pump which supplies air to the airometer from which theair isintroduced into the carbureter previous to mixing it with the gasolenevapors. The upper end of the rod 35 is loosely mounted in bracket b inorder to al low a certain amount of play of said rod which the movementof the bell-crank arm necessitates.

The stem 23 of the valve is screw-threaded and engages the screw threadsprovided on the interior of the shell or chamber 37 of the valve casing,whereby by the movement of the weighted extremities on the sleeve, ittravels endwise either in' one direction or the other according entirelyto the movement of the air-pump.

To regulate the quantity of hydrocarbon delivered from the tank 8 ofthe'carbureter, I

provide a valve 33 located on the supplypipe 19 which communicates withthe gas chamber 20. Thus the volume of the flow may be regulated bymanual operation of said valve 33, and the period of such llow will begoverned automatically by movement of the air-pump up and down whichoperates the bell-crank loosely mounted upon the stem of the valve,which in turn operates the weights on the valve-actuating arms andsclilopens and closes the feed valve automatica y.

c is a ca ed filler i e for sn 1 in h drocarbon is? the tank? p P y a yThe star 18 may be formed with a gas body 38 and radiating arms 39 ofperforated pipe sections provided with caps 40 at their ends.

The perforations 41 for spraying the hydrocarbon are arranged along thesides of said ipes, so as to spray the hydrocarbon, eve y over thescreen 17. I

42 is a valved outlet .i'er drawing oll' any hydrocarbon that may passthrough to the bottom of the air chamber 9.

When the machine is properly installed and connected with the housepiping for the distribution of the gas to the places of consumption, thelighting of the lights, stoves or grates causing or opening a vent forthe escape of the gas starts the machine by causing the air to pass fromthe airometer into and through the carbureting chamber, where it comesin contact with the hydrocarbon, causing the air to become-charged withthe hydrocarbon, so. forming. gas which passes out through the outletpipe 21 to the places of consumption.

The descent of the airometer operates a lever, not shown, which in thewell known way operates a valve, not shown, allowing intofthe cylinderin the air pump, causing i the air-pump to act and automatically suplythe airometer with air to take the place of that which has been used inmaking the gas, which has been consumed. This action will continue aslong and in the proportion of theamount of gas used, and the turning offof the lights, stovesor grates will stop or close the vent and so stopthe operation of the gas making process.
